DOUGH-MOLDING MACHINE.

incinta.

T0 @ZZ whom it' may concern Be it known that I, MORRIS HAYMAN, a citizen of the United States, residing at New York city, in the county and State of New York, have invented certain new and useful improvements in Dough-Molding Machines, of which the following is a clear, full, and exact description.

This invention relates to apparatus for cutting out a formation of dough from a mass, so that it may be transported to a rising table or a baking pan.

The object is to provide a machine which will operate accurately, and produce uniform rolls, bread or cake, as the case may be.

In carrying out the invention, I provide a carriage provided with a multitude of depending twopart molds from its under side, the two-part molds having operative mechanism in the carriage body to cause them to be operated simultaneously, to bite into the dough uniformly, and to retain the dough so that on lifting the carriage and moving it away a multitude of dough units all of similar shape, and size to their molds, may be with one operation placed upon a rising board or the like. In the specific embodiment of my invention shown, the molds each consist oftwo heinispherical parts pivoted near their vertical diameter to supporting rods on the carriage. Each mold is provided with lugs, to which curved connecting links are attached, the other end of the connect-ing links being pivoted to a gear wheel, all gear wheels of all the molds being properly meshed, so that a single operating motor or hand wheel can simultaneously open or close the two-part molds. Vhen open, the carriage and molds by the weight of the device will drop on to the bed of dough, the lower ends of the molds resting on the dough cause the dough to enter between the two hemispherical parts so that the operator may close all of the molds while in such position; then by lifting chain or the like, move the carriage off the dough and over the rising table or baking pan, where the molds may be released, dropping the dough in position for the next operation of the baker.

The scope of my invention will be pointed out in the claims.

As shown in the accompanying drawings: Figure 1 is a side elevation of my improved device. Fig. 2 is a plan view of the same with the chains shown broken away.

Application led March 26, 1913.

Patented June 23, 1914. Serial No. 756,841.

The dough 1 is placed on a mold board 2, and either first rolled out into the shape shown in F ig. 1 by any desired means, or the carriage 3 may be provided as shown with a pair of rollers 4 or 5 supported in vertical supports 6 and 7, which at this time may be locked in the position shown by bolts 8 and 9 entering bolt holes 10 and 11 in transfer rods 12, forming part of the supporting legs 6 and 7 A lever 13 secured to a disk 14a, to which both levers 8 and 9 are also pivoted, serves to withdraw the bolts or lock the same in place. When locked in place in the position of Fig. 1 the weight of the entire carriage will rest upon the rollers so that on moving the heavy machine backward and forward the dough will be flattened out effectively. `When this has been accomplished the lever 13 will be thrown to unbolt the bolts and permit the carriage and .its moldsl to drop on to thedough. The carriage 3 is provided with parallel transfer rolls 14, into which there are secured a number of depending studs 15, each stud below the carriage being pivoted to lugs 16 near the diameter of the hemispherical molds 17 and 18. Between two adjacent rolls 14 there is mounted for each two-part mold a gear wheel 19 provided with crank studs 2O and 21. Connecting levers v22and 23, which are bent around the shaft 24, on which the gear is mounted, serve to connect the studs 20 and 21 with lthe lugs 15 and 16 on the molds. Each set of molds in a line may be on the same shaft 24, but each provided with its own gear. Other parallel shafts 25 are arranged across the machine at right angles to the rolls 14, and at such a distance apart that the gear wheels on one shaft will mesh with the lgear wheels on each adjoining shaft, so t at all gear wheels will turn in unison with shaft 26, which is a central shaft, and to which its gears are secured. A hand wheel 27 on a central shaft 26 serves to operate the molds to close them when the wheel is turned in the direction of the arrow in Fig. 1. A lever 28 fast on the shaft 26 is connected by a spring 29 with a stud 30 on the carriage frame against the tension of which spring the molds may be closed by the hand wheel, and when so closed and the hand wheel is held closed the whole device may be transferred to the rising table or other device when, upon releasing the hand wheel, the spring will quickly open the molds until the lever 28 hits the stop 31,

preferably with a blow sufficiently strong to cause all the molded units to drop immediately on to the table. Chains 81 from bolts 32 at the four corners of the carriage unite with a chain 33 which travels over overhead idlers 34-35, and is provided with a hand loop 36, which may, if desired, be hooked over a hook 37 on the carriage to hold the device in suspended position. The lift and drop of the carriage may be controlled by the hand loop 36 in the chain 33, of which a loop 37 may be provided to regulate the height which this machine may occupy.

1 prefer to make the molds hemispherical, although any shape may be used, and l prefer that one mold shall have an under-cut rim 38, while the other has a projecting rim 39 to fit the under-cut rim of the other part.

In carrying out this invention, details of construction may be varied from those shown, and yet the essence of the invention be retained; some parts might be employed without others, and new features thereof might be combined with elements old in the art, in diverse ways, although the herein described type is regarded as embodying substantial improvements over such mdiications. j

As many changes could be made in the above construction, and many apparently widely different embodiments of the invention could be made without departing from the scope thereof, it is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted in an illustrative and not in a limiting sense. lt is furthermore desired to be understood that the language used in the vfollowing' claims is intended to cover all the generic and specific features of the'invention herein described, and all statements of the scope of the invention which as a matter of language might be said to fall therebetween.

By the term molds as used in the specification, I intend to use that term in a broad sense to cover any device which may be caused to penetrate int-o the dough to provide a pair of open jaws which may be closed, and lifted with a portion of the dough between their lower edges, and then j opened at a: later stage of operation to deposit the dough as has been described. It is not essential in all instances that the two parts shall be closed throughout when in contact one with the other, as it might be open-ended without in any way affecting the ability to grab the dough and retain it during the lift.
